The discount does not matter if you don't know the price

Orange juice

I bought a bottle of fresh orange juice. Unfortunately I don't want to drink it right now. Although I had planned to do so. So should I do it anyway and risk being disappointed by the lack of previously planned satisfaction? Or rather keep it hoping that I will want it soon enough?

Obviously, I am not living in the right way. Otherwise, I would have everything others want for me to have.
